'High risk' of severe weather in plains states

The National Weather Service's Storm Prediction Center has expanded the area of Oklahoma, Kansas, Texas, Arkansas and Missouri that it says is at high risk of severe weather that could include tornadoes.

The highest risk area for severe weather Tuesday now extends from north-central Texas across all of Oklahoma except the far southeast and the western third of the state into south-central Kansas. Also included is far northwestern Arkansas and far southwestern Missouri, where a Sunday night tornado is blamed for nearly 120 deaths.

The prediction center says there is a moderate risk of severe weather and tornadoes extending from northern Texas to central Kansas, northwestern Arkansas and southwestern Missouri.

The severe weather could also include wind gusts of 55 to 75 mph and nearly baseball-sized hail.
